b. Electrically Heated Models ONLY
The only electrical input connections to the dryer are the 3-phase (3ø) power leads (L1, L2, L3, and
sometimes neutral) and ground. Single-phase (1ø) power for the control circuit and for any single-
phase (1ø) motors (if present) is done internally to the dryer by the factory at the oven contactor.
No single-phase (1ø) input connection is required on a 3-phase (3ø) dryer.
CAUTION: THE DRYER MUST BE GROUNDED. A ground lug has been provided for this
purpose.
Input connection wiring must be sized properly to handle the dryer's current draw. This information is
printed on the dryers data label.
IMPORTANT: A separate circuit serving each dryer must be provided.
The electrical input connections are made at the electric oven contactor located inside the assembly at the
rear center upper section of the dryer. The ground connection is made to a copper lug also provided in this
area. To gain access, remove oven rear service cover.
IMPORTANT: A strain relief must be used where the input wiring enters the oven assembly.
